' The present invention relates toapparatus "forapplymg coatlngs to such surfaces as the faxing areas and bottoms of shoes and is illustrated as embodied in apparatus of the a type disclosed in United States Letters Patent No. 1,476,047, granted December 4, 17923, on my application, 7

The machine disclosed in the above-mentioned Letters Patent includes a member mov- 1O able, as by rotation, to apply a coating to the Work and independently movable, as angularly and bodily, to vary the application by change in position ofthe Work. Heretofore, this positioning movement has been produced Wholly through effort on the part of the op- Direct control of the member by the operator is also preferably provided for, an additional treadle being shown for this purpose.

I provide an applying member having a relatively small contact surface and comprisinsr,

as illustrated, a conefurhished by a helix,

adapted to carry a body of the coating substance Within it and at the same time perform "the conveying function. In the use of such an applying member, the point of supportof the helix is important, it being found that if the supporting member is carried entirely through the cone, so that its apex is closed, the travel of thecoating substance along the applying; surface is interfered with.

The frame of the machine iriclude'sa column 10 provided with an overhan ing arm 12" extending forwardly from the column. Journaled in this arm-is a h rizomalrubu lar shaft 14;, at the forward extremity of Which is mounted applying roll 16.; This roll has a frusto-conical applying suliface, preferably provided by a circumferential series of helical springs 18 extending between heads at the extremities of a body-portion20 (Fig. 5). Poiv er maybe furnished to rotate the shaftlj from a motor22attached near the lower portion and at the rear of the col- Fig. 3, parts being broken- We View s he bottoifia speed considerably lessthan that of the tions of the helix.

motor 22. As in the prior patent, the roll 16 is also oscillated at a greater speed than that of the movement of rotation just de scribed, by. lever mechanism 32 actuated by a cam-disk 34 fixed upon the frame. As a result .of this, the rotation of the roll is alternately accelerated andv retarded to more effectually rub the applied coating'into they work, and to better distribute'it at seams or other elevated ordepressed portions.

Associated with the outer head of th'e roll 16 is a rotatable, yieldable feed and gagewheel 36, the direction of rotation of which is opposite to thatof the rol1,so that while i the work is being advanced by the engagement of the wheel, the periphery of the applying roll, moving in the reverse direction, produces an effect of brushing out the coating over the area acted upon. The wheel 86 is mounted upon a shaft 38 extending through the tubular shaft 14 and having a bearing 40 trunnioned upon the outer side of the easing 28, this permitting the feed-wheel to rise under the pressure of the work, so the latter may be brought into effective engagement with the applying roll. Rotation is imparted to the shaft 38 from the shaft 26 by reduction-gearing 42, 44, the intermediate ele ments of this being fixed upon the inner end of an idler shaft 46 journaled horizontally .in the casing 28. I V I Below the roll 16 is a device which may both serve as a work-rest and as a means for applying cement to the bottoms of the shoes the foxing-areas of which are to be coated. This device includes a roll furnished by a conical helix 48 mounted upon a spindle 50 (Figs.'2 and 5). .The spindle has, at its lower extremity, a flange 52 (Fig, 5), upon which the bottom of the helix rests, and at its upper extremity an enlargement 54 engaging the interior of a convolution of the helixbetween theends of the helix. The spindle is journaled in and extends upwardly from the bottom of a receptacle'56, the inclined bottom wall 58.0f which directs'cement falling upon it'to the '"loWer convolu- The manner of supply-50f the cement to the rolls.48 and 16 will be later described. Fixed upon the spindle 50, be-

low the bottom of the receptacle, is a spiral gear meshing with a like gear 62 upon a shaft 64 journaled in depending portions of the walls of the receptacle. This shaft is joined by spiral gearing 66 to a sectional shaft 68 extending horizontally from front to rear of the machine and having its parts splined together at 70 (Fig. 2), to permit the move ment of the receptacle, which will later be developed. The shaft 68 is coupled by a universal joint 7 2 to a short shaft 7 4 rotatable in the rear wall of the casing 28. Fast upon the shaft 74 is a pinion 7 6 driven through an idle pinion 78, which meshes with a gear 80 upon theshaft 46. As the roll 48 is rotated by the connections just outlined, cement flowing upon its lower convolutions from the bottom 58 of the receptacle 56 is elevated by the spiral, passing upward both between the convolutions and through the interior and overflowing at the apex, the excess not used upon the work returning to the receptacle. The opening at the last or upper convolution permits thisconveying action without interference, the cement passing the enlargement 54 by traveling between the turns of the helix until it gains the open central portion .above thehead.

Variations in width of the foxing-area, or in the contour of this portion of the shoe operated upon, render it desirable to shift the roll 48 bodily along the roll 16, and also to change its angular relation thereto, turning it about its apex. To permit these changes to be made, the receptacle 56 is secured at the outer portion of a carrier 82, from the sides of which extend, rearwardly and upwardly, arms 84, 84 containing grooved arcuate guides 86, 86 (Fig. 8). Into the grooves extend pairs of projections 88, 88 fixed in forward extensions 90,- 90 of a carriage 92 movable in ways 94 at the under side of the'frame-arm 12. When the carrier 82 is oscillated by virtue of the travel of its guiding grooves over the projections 88, theangular position of the applying roll 48 is altered, the movement occurring substantially about the apex of the member as a center. Upon movement of the carriage 92 in its ways 94, a movement of translation is imparted to the roll 48, shifting its apex back and forth across the adjacent surface of the roll 16. The first movement so changes the relation of the Ill) work-engaging surface of the roll 48 in accordance with the contour of the portion of the shoe being operated upon, that contact 'may be had with a shoe-bottom along dif I" ferent portions without altering the effective action of the roll 16 upon the foxingarea. The bodily travel of the roll 48 along its companion varies the width of the band segments 100 meshing with corresponding segments 102 upon the portions 86 of the carrier. Loosely turning about the shaft 96 in a clockwise sense, as viewed in Fig. 3 is a sprocket-Wheel 104 connected by a chain 106 to a sprocket-wheel 108 fast upon a shaftllO Theshaft 110 is mountedt ansversely,.to rotate in thecolumn 10, and'is driven by bevel-gearinglll. (Fig. from the shaft 26. The chain 166 may be kept tautin the travel of the carriage by a roll 112 engaging its inner side, and "carried upon an arm 114 turning loosely upon the shaft 110. A spring 116, extending between this arm and a casing 118, partially enclosing the sprocket-gearing, maintains the roll in yielding engagement with the chain. Arranged to. turn a-boutthe shaft 96, andcontacting frictionally at 120 with the outer face of the sprocketwheel 104, is the cylindrical hub of a lever122. Upon the outer extremity of the hub is a cam-face 124 co-operating with an opposite face 126 upona sleeve 128 fixed upon the saaft.

Relative rotationina direction to seoarate these cam-faces is limited by contacting suris secured upon the'rod 134, and is movable thereby against the under side or the bloclr132 to turn the lever 122 in a clockwise direction, a s viewed in Fig. 3 of the drawings. Aspring 140 joins the lever 122 to a collar 142 secured near the lower portion of therod 134, this spring acting to so turn the lever that its surface 124 is normally relieved from pres sure againstthe companion cam-surface 126. Movement of the collar 142 to different points upon the rod permits the tension of the spring tobe varied. Turning with the sprocket-wheel 104 is a clutch-disk 144 (Figsbfil and 6) having a co-operating disk 146 fast upon the" shaft 96 and driven from the associated disk when these elements are forced into engagement withan' interposed friction member 148. A torsion-spring 150 (Fig.3), surrounding the shaft 96, acts in a counter-clockwise direction, as viewed in Fig. 3,"and exerts its force to hold the shaft, driven disk 146 and arms 98 in theirnor mal positions, in which the roll 48 cated as illustrated in 2 and 3 of t .16 drawings; When the operator depresses ings 162.

146. The friction material 148 thereupon I communicates the clockwise rotationof the sprocket-wheel and disk 144 to the shaft 96, turning the arms 98 up, and, through the gear-segments, movingthe carrier 82 over its guiding projections 88. As long as the operator continues to move the treadledown and thus revolvethe.cam-surface 124,.1131118 effect is maintained; but as soon as the treadl'e movement is stopped, rotation ofthe shaft carries the surface '126 away from the opposite surface 124,.the engagement wi-th which causes the pressure .between the clutch-disks 144 and 146, and the rotation stops. 1f the operator removes his foot from the treadle, gravity 015a spring, the latter notbeing shown in thedrawing, caries the treadle and rod 134 to their normal positions,-the shaft 96, with the elements secured thereto, and therefore the carrier 82,

being returned to normal by the spring 150. lit will consequently be seen that, by no greater effort than is. necessary to overcome the weight of the treadle 137 and rod 134, the operator controls the action of the iechanismi to oscillate the carrier and A e the angular position of the applying roll 48, this change being proportionateto the movement ofthetreadle.

Depending upon the character of the work, it maybe necessary also to move the roll 48 inwardly along the roll 16, to increase the effective coating surface ofthe latter. The power mechanism may also be caused to accomplish this, either. simultav neously with and throughout the just-do scribed angular movement, or during a portion of such movement under the control of settable means 164, to be described. Mount ed'to turn upon the shaft 96is a lever. 154 i (Fig. 8), upon the lower extremity of which is carried a gear-segment 156 meshing with a rack 158 fixed upon a portion of the frame. Upon the upper end of the lever 154is a segment 160, in which is a series of open These are arranged with their centers along an are for engagement by a springqiressed pin 164 movable horizontally through an arm 166 mounted to turn about the shaft 96 between. the lever 154 and the disk146. At the inner side of this disk 146 is a projection 168 extending into the same vertical plane as the lever'166. If the pin 164 is placedin the first of the openings 162, or that toward the front of the machine, the arm 166 is substantially in normal contact; with the projection 168. Consequently, when the movement of the disk 146 begins under the influence ofthe power mechanism made effective by depression of the treadle 13?, engz genient of the arm by the projection at once turns the lever 154aboutthe shaft. The lever is thereby caused to rock upon the rack 158 asa nucrum, and the carriage 92 is slid toward the for example, to the last of a series, contact between the projection 168 and the arm 166 may not occur during theangular movement of the roll 48. Consequently, there is no movement of translation imparted to it. For intermediate adjustments of the pin, the two movements may be differently combined, a certain amount of oscillation being imparted to the roll, followed by a combined movement of oscillation and translation.

The carriage 92 may be moved entirely by. the effort of the operator to shift the roll 48 bodily, by a treadle 170 (Fig. 1) connected by a vertical rod 172 to a block 174 pivoted upon an arm 176. This arm is secured upon a sleeve 178 turning loosely about the shaft 110 (Figs. 3 and 4). The rod 172 is connected to raise the block 17 4 yieldably by a helical spring 180 surrounding the rod and supported upon a collar182 fixed to it. A torsion-spring 184 encircles the shaft 110, and has one end hooked over the arm 1'76. This spring maintains the arm normally at its lowest limit of movement, this being variable by a screw 186 threaded through a depending port-ion of the arm and contacting with the frame. The adjustment obtainedby the screw determines the normal position of the roll 48, and thereforethe width of the roll 16 presented to the work. The sleeve 17 8 has upon it another arm 188, (Fig. 4) forked at 190 and engaging a hori- Zontal pin 192 carried by lugs at the rear of the carriage 92. Upon depression of the treadle 170 by the operator, the rod 172 forces the spring 180 against the block 17 4 i to rotate the sleeve 178, and, through the arm 188, slide the carriage in its ways to an extent determined by the amount the treadle is depressed.

The cement or other coating substance is contained in a tank 200 carried upon the upper surface of the arm 12 and having a discharge-opening controlled by a rotatable valve 202 (Fig. 2). As in the previous apparatus, there is delivery from this tank to both the upper portion of the roll 16 and to the roll 48, the coating substance in the latter instance dropping upon the bottom 58 of the receptacle 56. Here it is raised by the convolutions of the roll 16 along its outer surface to the upper extremity, for application to the bottom portion of a shoe held against the roll. The receptacle 56 is pivoted at 204 to the carrier 82, being held in the normal operating position by a springpressed pin 206 (Fig. 3) movable through opening the valve.

of cement may be caused to occur before the one of the arms 84 of the carrier. VViththe receptacle raised and locked in place by the pin, the roll 48 rotates in a vertical space 208 between the forward extremities of the carrier-arms. To allow the receptacleto be emptied, and to facilitate the removal of the roll for cleaning, the pin may be withdrawn from the registering opening in the receptacle, and-this swung downwardly upon its pivot, tilting the roll forward through the opening 208 clear of the carrierarms.

Sometimes manufacturers prefer not to coatthe entire shoe-bottom at the time of cementing the foXing-area, but merely to apply a coating to the edge of the bottom adjacent to the foxing. work-supporting shield 210 (Fig. 3) is secured to the front of the carriage by screws 212 extending into the arms 84 through slots.

214, theseslots permitting the ready removal of the shield when the screws are loosened. The shield has side portions resting against the forward extremities of the arms, and a curved portion 215 generally conforming to the roll. This portion 215 acts as a fixed or non-rotatable gage-surface or work support which is interposed between the bottom coating roll 48 and the bottom of the shoe, and protects the inner portion of a shoe-bottom applied to it from the coating action of the roll. Under these conditions, only the edge of the shoe-bottom receives the application of cement, this being from the tip of the roll 48, which projects above the shield. Removal of the shield upon loosening the screws 212 exposes the work to the action of the entire length of the roll.

To govern the flow of cement to the rolls, the valve 202 has secured to it an arm 216 (Fig. 1), to which is pivoted, for ready separation, a rod 218. The lower end of the rod rests in the other depression or cup 220 at the forked end of the lever 135 beyond the link 136 connecting the lever to the treadle 137, which controls the power mechanism. Therefore, when this treadle 187 is lowered to apply power to change the position of the roll 48, the rod 218 is raised by the lever 135, This starting of the flow shifting of the roll, by the lost motion introduced by the spacing of the collar 138 from the block 132. To open the valve when the other treadle 17 O is depressechthe rod 172 carries, adjustably fixed upon it, a contact member 222, which bears against a collar 224 secured to the rod 218 above the contact member. A tension-spring 226, connected to the base of the machine and to a collar 228 socured upon the rod 218, holds the valve nor- To this end, a rigid desirable, places the pin 164 in such a one of i the openings 162 as will provide for an increase in this width under the influence of the power mechanism. The treadle 137, if the operator is to utilize the action of the power mechanism in positioning the roll 48 is depressedto, an extent which will carry the roll initially to the desired point. A shoe to be cemented is 'thenipressed against the feed-wheel 36, as is illustrated in Fig. 5, this advancing the work against the rotating surface of the roll 16, and at the 'sametime serv ingas a gage to producea clean-cut line of demarcation between the coated and uncoated areas. 7 The bottomof the shoe rests against the receptacle 56, from, which it is raised by" thehelix'to the point of the-applying roll 48.

Continued downward movement of the: treadle to the extent, desired actsthrough the rod 134 to clutch together, under the influence of the cam surfaces" 1 24 and 126, the driving and driven disks 144'and 146,- respectively. By' these,-the shaft 96'is rotated to varythe angle of the roll 48, and at the same time, or as the angular' m-ovement progresses, the carriage 921is shifted' by contactof the projection 168 with the arm166 (Figs. 3 and 6),to carry the roll 48 (and. the shield 210, if it is used) across the roll 16, thereby to determine the width of the foXing-area to be coated;- When themovement of the treadle 137 stops, the driving action ofthe power mechanism is also discontinued by the sepa-k ration of the cam-surface124 from the surface 126. *Ifthe conditions surrounding @the justing movement of the roll 48} desirable,
